I really liked Amelia. I found her to be a really strong, determined woman who wants to do the right thing. Because of who she is, she didn't just deny things outright to the reporters, but that put her into a situation where the engagement appears to be real. She had briefly considered going through with it, as she and James are friends, but once she discovered her pregnancy she knew it couldn't happen. She also wanted to tell Quinn face to face, hoping that they would be able to work things out. I loved her ingenuity in getting away from the reporters and making her way undetected to Quinn's ranch. She was devastated to find out just how angry he is and how unwilling to listen to anything she has to say.
Quinn had thought that what he and Amelia shared meant something to her, but hearing of her engagement when she returned to England brought back terrible memories of his ex-wife. She had left him to go back to her old boyfriend, leaving him doubting his judgment in picking a woman to love. To have Amelia appear to do the same thing just made it worse. When she came back to see him he didn't want to hear what she had to say, not trusting her at all. When he finds out about the baby he wants them to marry, making sure that the baby has his name. Quinn's father had been illegitimate, never acknowledged by his father and he didn't want the same thing to happen to his child. Quinn also has a huge issue with the economic gap between himself and Amelia, again because of his grandfather's treatment of his father. He just couldn't see that Amelia didn't care about it.
Amelia is deeply in love with Quinn and would gladly marry him if she thought that he cared also. His constant anger with her has her convinced he doesn't care for her and she refuses to have a loveless marriage. She is also determined to stay in Texas so that Quinn is fully involved in the baby's life. I loved the strength she had in standing up for herself and her own needs, while at the same time trying to give Quinn what he needed.
